Abstract: A method for producing an all-solid multilayer battery, and an all-solid multilayer battery. The all-solid multilayer battery may be produced by depositing, by electrophoresis without any binder, at least one anode layer, at least one electrolyte layer, and at least one cathode layer. The at least one electrolyte layer, and the at least one cathode layer are obtained from a colloidal suspension containing nanoparticles that are not agglomerated with each other to create clusters and remain isolated from each other.
